Question: 1 / 400

What is a common effect of a dysfunction in the vestibular system?

Visual impairment

Dizziness

A common effect of dysfunction in the vestibular system is dizziness. The vestibular system, located in the inner ear, plays a crucial role in maintaining balance and spatial orientation. When this system is impaired, it can lead to sensations of vertigo or dizziness, as the body struggles to integrate signals regarding position and movement. This dysfunction may result in a mismatch between what the eyes see and what the inner ear detects, causing individuals to feel unsteady or disoriented.

Visual impairment and tinnitus can occur in some cases but are not direct consequences of vestibular dysfunction. Loss of smell is unrelated entirely to the vestibular system, as it is associated more with olfactory function. Hence, dizziness stands out as the primary and most common symptom associated with vestibular issues, making it the correct answer in this context.
